\ apparatus assembled together in one concrete or unit machine capable,by special adjustments andarrangements, of the several particularfunctions or operations hereinafter de- 'scribed,-and furthermore, toproduce a ma- "chine of this class which shall be simple and compact inconstruction, easy of interchange and adjustment, efficient in itsseveral distinct operations, durable in use, accessible andinterchangeable in all-its essential parts,

and comparatively inexpensive in cost and maintenance. For theattainment of these objects, and for other purposes hereinafterenumerated, myinvention' consists, in brief, in certain details ofconstruction, arrangement and combination of parts, all of which will bemore fully described hereinafter, and the specific points of novelty inwhich willbe pointed out in the appended claims. 7

In the accompanying drawings, I have shown certain features and partswhich I deem adequate for successfully carrying out my inventioninpractice, however, it will be clearly manifest that numerous minorchanges, variations, and departures may be made without deviating fromthe spirit and scope of my invention as long as the fundamentalprinciples of the same are adhered to,

which principles are defined and set forth in the claims.

Referring to the said drawings forming a part of this specification:-Figure 1 is a top plan view of the complete machine as used as ahay-rake and side-deliveren'the latter mechanism being connected with aloader (not shown), or adapted to deposit the raked hay along the lineof travel of the apparatus. Fig. 2 is a longitudinal vertical sectiontaken on the plane indicated by the line a'-.'r Fig. 1.

Fig. 10 is a detail sectional view through thecenter of the forward portion of the machine, showing the arrangement ofthe elevating levet and its co-operating devices. Fig. 11 isa rearelevation, partly in section, illustrating the construction and mannerof supporting the roll at and above the edge of the side-delivery apron,which roll carries traveling conveyer-bands operated by the maincylinder. Fig. 12 is an enlarged detail section of one of the drivingWheel hubs. Fig. 13 is a detail front or face elevation of Fig. 13; andFig. 14 is a detail View showing the end of the side deliverer and thegearing for driving the same from the main axle.

Like letters and numerals of reference indicate the same orcorresponding parts in the various views of the drawings.

The frame-work of the machine and other stationary and merely'auxiliaryparts are of such shape, size, strength, configuration, and material asfound necessary or desirable under the demands of practice to supportthe incu mbent and operating parts in their proper relative andcooperative positions; and therefore, the said frame-work, &c., maybechanged and varied to correspond with such changes and variations in thestructure as occasioned by experience or practical tests.

Referring to Figs. 1, 2, and 11, A, A, are the two side-beams of theframe, extending longitudinally on both sides of the machine,respectively, and are braced and held together rigidly at their frontends by crossbeams, B, B, and supported at their rear ends by themain-axle, C, carrying at each extremity a drive-wheel, D, and mountedin bearings upon the side-beams, A, A. The length of the main-axle, andthe distance the side-beams are spaced apart approximately equal thewidth of the raking mechanism; and asIdesire in practice to makemachines of various raking widths, it will be obvious that the length ofthe main-axle is varied to suit the requirements, such as the variouswidths of mowing machines. The hub of each drivewheel, D, is preferablyof cast-iron with wrought iron spokes, E, E, secured in the hub at theirinner ends, and at their outer extremities severally riveted into therim or tread,F, of the drive-wheel. As shown,these spokes are set apartat their inner ends, and at their outer terminals are arranged in acommon vertical plane to give strength and rigidity to the wheel, seeFig. 13. On the outer face of each hub is secured a diskshaped cap, G,comprising an inwardly projecting horizontal circumferential flange, a,forming a circular recess on the inner face of the cap circumscribed bythe flange, a, and a central outwardly projecting horizontal circularboss, I), longitudinally pierced by a circular bore, 0, for the axle.This cap is slipped over the hub proper in the manner shown in Fig. 13;and the adjacent periphery of the hub is provided with a series of teethor notches, (Z, (Z, designed to be engaged by the spring pressed dog s,H, II, pivotally attached to lugs, e, e, which, in turn, are fastened tothe flange, a. The dogs are held in engagement with the teeth on the hubby a band-spring, f, one for each dog, at tached rigidly at one end by arivet to the flange, a, and having its free end exerting tension againstthe side of the pawl or dog. The cap, G, is keyed to the main'axle bythe key-pin, I, consisting of a bolt fitted with a nut. By thisconstruction, the drive wheels are prevented from backward movement yetare free to revolve in the opposite or forward direction.

The side-beams, A, A, are severally supported on the main-axle inside ofthe hubs of the drive-wheels, by ordinary boxes constituting bearingsfor the axle; and inside of each side-beam and in proximity thereto is asprocket'wheel, J, or J, keyed rigidly to the main axle, thesprocket-wheel, J, driving the raking mechanism through the medium of achain-belt, while the sprocket-wheel, J, imparts motion to thesidedeliverer -in a similar manner. Inside of each sprocket-wheel is anordinary clutch-device, K, one being shown in dotted lines and the otherin full lines in Fig. 7. By means of this clutchmechanism, eithersproeket-wheel may be thrown out of engagement with the mainaxle, aswill be readily understood.

L indicates a chain-belt running over sprocket-wheel J at the rear, andfitting over and communicating motion to the sprocketwheel, M, on therotatable cylinder-shaft at the front of the machine. N is anidlersprocket or belt-tightenerjournaled on its adj acent side-beam, andserving simply to maintain the belt in an engagement with the spurs ofthe sprocket-wheel, J. For this construction see Fig. 2. As shown indotted lines in said figure, the arbor upon which the idlerwheel isjournaled is made transversely movable and adjustable by being seated inan elongated slot, g, in a cast-plate, h, bolted to the side-beam,whereby the idler can be adjusted to vary the tension of the chain-beltby any ordinary device (not shown).

Referring now to Figs. 1, 2, 4:, 9 and 10, O, is a stationary shaft ofthe raking cylinder fixed and supported at its respective extremities instirrup-boxes, P, P, on the side-beams. As will be seen in Fig. 4, thelower half of each box, P, is provided on its under side with an angulardownwardly projecting pointed tooth, I, which is driven down into thewooden side-beam and serves to keep the boxing there in place. Inaddition to this, the lower section of each box may be bolted to theside-beams to prevent any possibility of displacement. The shaft, 0, ispreferably hollow or tubular throughout its length, and accordingly, Imake the same of a section of ordinary gas-pipe of sufficient diameterand strength, and of such length as to terminate at each end flush withthe side beams of the frame. Approximately at each end of the shaft, 0,and also at its central point, is mounted thereon a stationary sectionalboxing, Q, which I shall specifically term herein a spacing boxing owingto its peculiar function. Each of these boxings is made in two halves,each semi-cylindrical in shape, and bolted through the main-shaft byrivets passing through both halves of both boxings, and also through thecylinder-shaft. The heads of the rivets are countersunk to be flush withthe exterior surface of each boxing, see Fig. 4. There are threeboxings, I, on the cylinder-shaft,one in the center, and tworespectively near its extremities. One end boxing is about three inchesfrom its adjacent side-beam, while the other is about four inches. Overthe cylinder-shaft and its spaeing-boxings, is rotatably fitted a largergas-pipe or cylinder, R, and keyed thereto are three cylinder-heads orskeleton drums, 5,6, S"; the heads, S, and S, being severally on theextremities of the shaft, while the head, S, is mid-way the same. Thetwo end-heads are keyed directly over and in vertical alignment with theend-boxings, and each cylinder-head comprises a narrow metallic rim ortread, 71, held in position and stayed by radialspokes, 70, 7c,projecting from a central hub or web, 1.

hub is secured the key-pin, m, by which each cylinder-head is fastenedto the shaft, R. Transversely through each rim, t, are made fouropenings to receive and hold. the four transversely extending shafts, n,n, which, in turn, carry the movable raking teeth of the In a suitableaperture in the cylinder. These shafts, n, 'n, are held against endwisemovement in the openings of the heads by transverse limit-pins, n', n',respectively at the ends of said shafts, as shown. As will be seen by aninspection of Fig. 10, there are four spokes, k, k, and at a point nearthe outer end of each spoke is pivoted a spring-actuated pawl, 0,attached to the face of the spoke by a pivot-pin, p, and working againstthe tension of the bandspring, q, fastened at one end by a rivet to theside of the spoke, and pressing at its other free end against the curvedrear end of the pawl, 0. The forward curved portion of the pawl isprovided with a sloping notch or recess, 9", designed to receive andhold a detent on a trip-lever on the end of a raker-teeth shaft, ashereinafter explained.

On one side of the machine, the ends of the cross-shafts, n, n, projectthrough the perforations in the rim of the cylinder-head a prescribeddistance, and on such protruding ends are rigidly secured thetrip-levers, s, 8, each consisting of a strip of fiat-iron looped at itsrear end around the end of the shaft, doubled back upon itself, andthere bolted, forming a tight connection around the end of the shaft.This trip-lever is in a vertical plane slightly beyond or outside of theadjacent or corresponding pawl, 0, and to each trip-lever approximatelyat the end of the loop is fastened a lateral detent or latch, 15,adapted to enter into and engage the sloping recess, 7, in the pawl, 0.Each pawl is limited in its swing or movement by a stop-pin, u, on eachspoke, 7c, slightly behind the pivotpin, 19. On the end of thestationary shaft, 0, is rigidly secured the trip-roller arm, 1),fastened to said shaft in a similar manner to the trip-levers, s, andcarrying at its forward extremity a cam-acting roller, 10, journaledbetween the prongs formed on the end of said arm. The roller arm isarranged in the plane of the pawls, o, and projects out radially fromthe shaft in such position'that it will engage the curved rear ends ofthe pawls, o, successively as the latter begin to descend from theirhighest vertical position, and will throw the detents or latches, out ofthe recesses, r, just as the raker teeth, which are carried by thecross-shafts, n, deliver the raked up hay to the carriers. Theliberation of the trip-levers allows the raker-teeth (by the rotation ofthe shafts, n), to be folded forwardly upon the cylinder, out of the wayof the cross-bars of the carrier-mechanism, as the raker-teeth arecarried below the plane of the carrier and opposite the ground. They arereturned to their operative positions successivelybydevices hereinafterdescribed. This roller arm, 1;, projects at an angle of about forty-fivedegrees from a right-angle formed between a horizontal plane of theshaft, 0, and a vertical plane; and between such horizontal plane andthe lowermost vertical position of the raker-teeth is anotherroller-arm, z, fixed to the shaft, 0, in a manner similar to theroller-arm, andin the Verticalplane common to the trip-levers. At theouter end of the arm, 2, is fixed the roller, a, arranged in suchposition with relation to any descending trip-lever as to throw it backinto such a position that the detent, 23, will engage in the recess, 1',as it begins to near its operative raking position at the bottom of thecylinder. The raker-teeth b, b, are attached to the several shafts, n,n, at regular intervals apart, as shown in Fig. 4, and each tooth, b, ismade ofa single piece of elastic metal, such as rod-steel or iron coiledat its inner end around the particular shaft, n, and riveted there inposition, see Fig. 9. The outer ends of all the raker-teeth on eachshaft are in the same plane and project radially from their supports.Between any adjacent pair of teeth, 1), travels an endless carrier orband, 0', encircling the shafts, ran, at its forward end or turn, andrunning over a roll, d, at the rear of the machine, which roll is in ahigher horizontal plane than the cylinder at the front. Thus, it will beunderstood that there are a number of endless bands, 0', arranged totravelparallel and side by side over the raker-cylinder and the roll,01. These bands are tied transversely together by cross-bars, e, spacedapart equal distances and wide enough for the purposes of operation. Theconnection between the cross-bars, e, and the bands, 0' is made by thelatter being coiled around the respective bars by a single turn orconvolution. At each side of the machine the several ends of thecross-bars, e, e, are fastened to the belts or chains,f', which arecarried by the smooth treads, 1', of the end-cylinder-heads and the endsof the roller, (1. The treads, i, may be grooved to prevent the belts orchains from slipping laterally if .desired.

From the foregoing description, it will be apparent that as theraker-teeth carry up the hay the latter is delivered by the teeth to thecarriersand conveyed back to the rear by the same. At the same time thedelivery is made the trip-mechanism throws the raker -teeth out of rigidposition so as to permit them to fly back out of the way of thecross-bars which fit up against each set of teeth. Then, as suchraker-teeth descend coming nearer their renewed operative rakingpositions, they are again thrown into rigid or set position by theroller, a.

The first action of the tripping mechanism causes the raker-teeth to flyback and release the hay, as well as permitting them to be out of theway of the cross-bars. The roller, d, is journaled at both ends in theuprights or standards, n, n, and is divided centrally to permit thesprocket wheel, j, to be keyed in the annular recess thus formed betweenthe adjacent faces of the roller. This sprocket-wheel is keyed to theroller shaft, consisting of the gas-pipe, Z, running centrally andlongitudinally of the roll, see Fig. 12. A sprocket-chain, m, travelsover the sprocket, j, and the sprocket 721'" on the centralcylinder-head, S; and to this sprocket chain are secured the centers ofthe cross-bars of the endless carriers. In this manner motion iscommunicated from the cylinder to the roller, d.

The roller, 01, is supported centrally by the bifurcated casting, 0',consisting of the two bearing arms, pflp' serving as journal supportsfor the gas-pipe or shaft, Z, and the splayed attaching Wings, q, q,bolted to the apex of theinvertedV-shaped frame, r,comprising the twooblique standards 8, s, joined at their converging and abutting ends atan acute angle, as shown in Fi 12, and attached severally at theiropposite extremities to the side-beams, A, A. Thus the rear roller, cl,is supported at its ends by the vertical standaids, n, n, and at itscentral point by the casting, 0', on the frame, r.

Referring now to Figs. l, 2, and 6, the sidedelivery mechanism is placedtransversely of the machine behind the rear roller, (Z,and in a-lowerhorizontal plane than the latter so that hay carried back by thecarriers will drop by gravity on the side-deliverer, and be delivered bythe same either upon the ground or to the loading mechanism hereinafterdescribed. This side delivery mechanism consists of an endless apron orcanvas, 25, provided with surface cross-slats, to, extending across thewidth of the canvas, and spaced a certain distance apart. The carrierapron,t, runs over two rolls, 2;, 1;, respectively at the ends of theside-deliverer, each roll being suitably journaled at its ends in theside-plates, w, of the side-delivery frame. The framework of thismechanism comprises two backwardly extending extension-bars, or,attached severally at their inner ends to the ends of the side-beams, A,A, and serving as supports for the several parts of the side-deliverer.The side-plates, w, are removably fastoned in a Vertical manner to theextensionbars, m, and are each rectangular in shape with one extremitysquare while the other is chamfered or inclined, as shown. Thesetwoplates are spaced :1. distance apart approximately equal to the width ofthe carrier apron, and each is provided on its inner surface adjacent tothe edge of the said apron with a strip, y, bolted thereon and forming aguideway for the ends of the cross slats of the apron.

As shown in Fig. 15, motion is communicated to the side-delivery apronby means of a sprocket-chain, .2", running over the sprocket-wheel, J,at one end, and over the sprocketpinion, a", at the other end. Thepinion, a,

is keyed to a stud-shaft, b, journaled to the frame-work and carriesanother sprocketwheel, 0, which is connected to the sprocketwheel, 61',bya chain-belt, e. The sprocket, d, is on a counter-shaft, f, journaledon one of the side-beams, and carries a bevelgear, 9, intermeshing witha pinion, h, on the end of one of the shafts of a roll, 1).

t, 2'', respectively designate sid e-boards or guides of the frame ofthe machine, each made of the required material and in the desired shapeand dimensions. In front each side-board is fastened to the adjacentsidebeam by an angle-iron (not shown) which is bolted to the side beamand to the outer side of the board. At the rear, each side board issupported at the top of the end-frame in a suitable manner (not shown),thus occupying an inclined position. The ends of the rollershaft, Z,extend through slotted bearing openings in the rear ends of theseboards.

In Fig. 2 is shown a shield or guard embracing the end of the cylinderto keep the hay from being caught by any of the moving parts. Thisshield or guard is not shown in any other view and forms no material ofnovel feature of my invention.

70', indicate severallythe ground-wheels at the front of the machine,each of suitable size, strength, and construction, and journaled on therespective ends of the front-axle, Z,which in turn, is attached rigidlyat its center to a vertical shaft, m, passing up through a cross-plate,n, on the front-platform of the machine, and terminating in a forkedsupport, 0", for the roller, 19 This support, 0, is swiveled in the endof the shaft and between the prongs of the same the roller, 19', isjournaled. Over this roller passes achain, q, fastened at one end to oneof the crossbars of the frame, and at its other, attached to the windingdrum, 1'', trunnioned in endbearings in the frame.

8 is an arc-shaped rack-bar bolted to the platform, and serves to holdthe vibratory crank-lever, t, keyed at its lower end to the drum-shafhu,and provided at its upper end with a pawl-lever, 1;, having a pivotallyconnected lever handle, w", at its upper end, and jointed to thestop-pawl, x", at its lower extremity. By this construction, theoperator can, by swinging the lever in the proper direction, raise andlower the front portion of the frame-work to which the chain isattached, by winding or unwinding the latter about the drnnnr, therack-bar and operating lever serving to hold the chain in any desiredposition about the drum.

The front platform and framework of the machine are made of suitablestrength and configuration to suit requirements, having brace-rods,cross bars, foot-rests, &c. Onthe front-platform is an inclinedstandard, 2', secured at its lower end to the framework, and at itsupper end carrying an ordinary seat for the operator. The constructionof the parts just described is shown in Figs. 1, 2, and 11.

The draft-appliances are secured to the front-axle and are of anydesired or approved construction.

From the foregoing description, it will be understood, that by using allthe parts described, except the side-delivery apparatus, the hay can beraked up and passed back over the rear roller, cl, to the ground, thehay being lifted in advance of the center of the cylinder and carriedback in a continuous sheet. In this capacity the'maehine would be in thenature of a tedder for raking up the hay and aerating it; then droppingit lightly on the ground. With the side deliverer, it

would deposit the hay sidewise or laterally of the machine in acontinuous windrow.

The side-delivery-mechanism is made detachable from the rear end of themachine so that it may be readily removed according to the demands ofoperation by any approved or ordinary means (not shown).

In conjunction with the side-delivery rake I employ an automatic loadingmechanism which I shall proceed to describe in detail.

Referring to Fig. 3, 2 indicates an inclined chute which is fixeddetachably to the discharge end of the side-delivery frame, in anysuitable manner and it comprises the sideplates 4, 4, each made of sheetmetal such as steel with inturned guiding flanges to prevent thebellying of the endless carrier hereinafter described. The open lowerend of this chute communicates with the side-deliverer, and it is sosupported as to prevent sagging, any approved securing and bracingdevices being employed. Two endless aprons or carriers, 8, 8, arearranged to travel up through the chute with their inner adjacentsurfaces separated a prescribed distance and traveling in the samedirection, that is, upwardly. By means of these two carriers, the hay iselevated to the top of the chute and dropped into a wagon. The train ofsprocket-gearing is shown clearly in Fig. 3 so arranged that it givesmotion to the inner surfaces of the car riers in the same direction, andcan be varied and changed according to requirements. Such gearingreceives its motion from the roll, '0. The inner sides of theside-plates, 4t, 4;, are'provided with guide ways similar to those onthe side-plates of the side-deliverer, there being two guide-strips oneach side-plate, one for each apron or carrier. The aprons, 8, 8, areeach provided on their outer surfaces with spaced carrying slatsarranged corresponding to those on the apron of the side-deliverer, andhaving their ends in engagement with, and traveling under, theguide-strips on the inner side of the side-plates.

In operation, the hay is raked up by the slightly curved raker-teeth ofthe cylinder, and carried back by the endless carriers, 0, and droppedoff lightly behind the machine on the ground. In this operation, noappreciable amount of the hay is turned over, it being simply raked upand lightly and gently dropped behind the machine thus subjecting it toan aerating process, and leaving it on the ground in loose layersthrough which the air and sun can readily penetrate, thus facilitatingthe curing of the same. This method of handling hay that has beensubjected to a heavy dew or rain will be found greatly advantageous, andmoreover, will serve to loosen hay pressed down by the wheels of themower, or which has been trodden in a packed mass by the hoofs of thedraft horses.

When in use in the aforesaid capacity, my machine is in the nature of atedder.

The operation of raking the hay from the ground may be briefly set forthas follows: As the drive-wheels of the machine are making one fullrevolution, they travel about twelve feet, and now dividing the twelvefeet by four (there being four raker-teeth-shafts) I find a width ofthirty-six inches raked by one row of raker-teeth, and while the machineis practically stationary, one row of teeth willrake eighteen inches ofthe ground; thus, the raking is effected half by the rakercylinder andhalf by the forward movement of the machine, and the slight scrapingaction due to this movement presses the masses of hay closely together,and is thereby instrumental in producing clean and thorough work.

When the side-delivery attachment is in use, the machine is called aside-delivery rake. The object of throwing the hay sidewise incontinuous windrows is to deposit the same in a position thatasupplemental loader may convenientlycarryit upintoawagon. When theoperator desires to throw the hay upon the ground with theside-deliverer, the width of two swaths can be thrown into one commonwindrow by projecting one width of rake onto another, and then throwingthe two onto stubble. In the old forms of loaders a greater part of thehay is left upon the ground, but with my invention this difficulty isentirely obviated.

When my improved loader is in an operative position, the hay is takenfrom the discharge end of the side-deliverer, and conveyed to the top ofthe chute, from which point it is dropped into a wagon which is arrangedbeside and moves with the harvester.

The advantage derived from the arrangement of the loader, whereby itprojects laterally from, and is carried by, the harvester frame is asfollows:A hay-fork such as is ordinarily employed for transferring thehay from the wagon to the barn-loft is capable of lifting about one-halfof a wagon-load, that is, the front or rear half, at one time. When hayis deposited in the wagon from the rear end, it becomes twisted orintermeshed, and no dividing line is formed between the front and rearportions of the load. But when the loading is accomplished from theside, as contemplated hereby, (the wagon being driven abreast with theharvester and parallel therewith) the front half may be filled andsubsequently (the team being driven ahead sufliciently) the rear halfmay also be filled, thus enabling the load to be removed readily bymeans of a fork.

All the parts'of the machine are simple, durable and interchangeable,and can be kept in repair and operative condition by any unskilledperson. Suitable lubricating orifices ICC or devices are providedthroughout, and in deed, all mechanical expedients for efficiency andconvenience are present.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is
